[GEM-dev] [PD-dev] pix_opencv

[me.grimm]

hey antoine

i just tried your build and it didnt work. i get:

/Users/megrimm/Desktop/pix_opencv/pix_opencv_athreshold.pd_darwin:
dlopen(/Users/megrimm/Desktop/pix_opencv/pix_opencv_athreshold.pd_darwin,
10): Library not loaded: /sw/lib/libopencv_core.2.3.dylib
  Referenced from:
/Users/megrimm/Desktop/pix_opencv/pix_opencv_athreshold.pd_darwin
  Reason: no suitable image found.  Did find:
	/sw/lib/libopencv_core.2.3.dylib: mach-o, but wrong architecture
	/usr/local/lib/libopencv_core.2.3.dylib: mach-o, but wrong architecture

because your dylibs are not embeded in the folder (mach-o, but wrong
architecture errors are from my 64bit builds)

so this didnt seem to work?
